Escaping whitespace and parenthesis in filenames

[jehoshua]

I need to write a small script that creates 'ffmpeg' code and therefore need to escape whitespaces and parenthesis in the filenames.

Have looked at a few ways to do this and keep getting errors. Here is what I have tried

https://docs.python.org/3/library/shlex....hlex.quote

https://pypi.python.org/pypi/shellescape

This doesn't quite do what I wanted:

#!/usr/bin/python3

import re
import glob, os

for file in glob.glob("chunk*.txt"):
    print(re.escape(file))

Where the filename is chunk-the quick brown (fox) jumped.txt the output is

Output:
chunk\-the\ quick\ brown\ \(fox\)\ jumped\.txt

Where the filename is chunk-182.txt the output is

Output:
chunk\-182\.txt

I don't need the dashes or periods escaped, only whitespace, parenthesis and square brackets.

Use

import re
_to_esc = re.compile(r'\s|[]()[]')
def _esc_char(match):
    return '\\' + match.group(0)

def my_escape(name):
    return _to_esc.sub(_esc_char, name)

# file = my_escape(file)

Use .....

Thanks, that works just fine on whitespaces, left and right parenthesis and left and right square brackets.

#!/usr/bin/python3

import re
import glob, os

os.chdir("/home/somepath")

_to_esc = re.compile(r'\s|[]()[]')

def _esc_char(match):
    return '\\' + match.group(0)
 
def my_escape(name):
    return _to_esc.sub(_esc_char, name)
 
for file in glob.glob("chunk*.txt"):
    file = my_escape(file)
    print(file)
